For me personally, the winner is the port of Ubuntu Touch from Joel for the Xiaomi Poco F1 :

thanks, Joel, for your great work.

@josele13 Thanks for your detailed answer. Your profound advices are very helpful. I have to study this in detail.

Thank you both for your answers:

@arubislander: I I suppose Syncthing will solve my problem the easiest way. I use my phone since many years man.y for writing. There are thousands of files on my SD card which I don t want to loose. My main motivation to choose a Linux phone was that I expected an improve in file access possibilies. This is there, but mainly for progammers. Syncthing is also available for Android, and there are apps available to control mouse and keyboard in Android. Therefore I don t see a reason why to use a Ubports phone instead of an Android phone. Softmaker office on Android is as the desktop app.

The PinePhone has at least the option to write to the external SD card, and internal and external SD card can be acessed over Jumpdrive. This seems to me another easy solution.

@ pctrl : Thanks four your detailed instruction. Happy that this option works for your you. I saw some videos about SSH. It seems a bit too big for my application. It also seems that not many use their phone in that way, else it would be better implemented.

I also thought about a Rasperri Pi with Ubuntu desktop to get all the options, but it is not so handy. But I eventually will carry around such a device with an image of home assistant for sensor data acquistion, which is only available for Rasperri PI.

Thank you for your support .

@c0n57an71n I admit, this is an advantage of the PinePhone. I also miss a dual boot option for Ubuntu Touch. Some apps only work on newer Android releases. I currently carry around three different Samsung Galaxy S5 devices with different Android versions. Each for it's on purpose. One for ANT+, one for writing capability to the SD card, and one for phone calls the latest Android apps. With Ubuntu Touch, there will be one device more. Multi boot could solve the problem.

@flohack I don't agree with flohack. Even when developers are not present in the forum, every knowledge about devices is precious. For instance, there is a problem with the different types of Xiaomi devices, which their exact model naming. A subfolder for each Xiaomi device which is ported, or generally for each device which is ported would be helpful. Every port is precous work and deserves a subfolder, a subfolder for each device someone requests. Even if there is no further developement for a device, it is good to know the different devices, their naming, and what is working, and what is not working. This can help which device to choose. Else this information is scattered everywhere.

1. did you manage to install LibreOffice on your Ubports phone?

2. Do you use LibreOffice on your Ubports phone?

3. If so, which components of LibreOffice do you use?

4. Can you report bugs when using LibreOffice with your Ubports phone?

I don t have this device either, and I am not a porter as well, but I appreciate your work very much. Every contribution to the Ubuntu Touch community is helpful.

@tchan the developement of the Xiaomi Redmi 7 seems to make progress. Could you inform us, when the Ubports installer for the Redmi 7 is there?

@nero355 After intense tests, whe found out that it is possible to run LibreOffice on a PinePhone (PostmarketOS, but not Ubuntu Touch), also for non-developers. It is the option which has been tested the most, and was written about the most. There are issues left, but there also instructions to resolve these issues available. Developers welcome.

@luksus Thanks for sharing your experience. What a pitty. LibreOffice does not work on a Ubuntu Touch Pinephone, and now also troubles with Fairphone 3.

We had about three weeks to get LibreOffice to run on a PinePhone with PostmarketOS and mobian. After three weeks, when all troubles where described in great detail, it «just worked» in those distros. A miracle happened.

It is worth publishing issues. Distro developers eventually will update it.

Yes, this is the Ubports forum. It was about finding out whether it is worth to try LibreOffice on a Fairphone 3, after I had initial problems on a PinePhone with LibreOffice on PMOS.

I did distro hopping on the PinePhone and went through all possible distros, until I managed to install LibreOffice. I also have a Fairphone 3, which I bought before the PinePhone, and I changed to the PinePhone since I can write to the external SD card which I really love. I don t think I will buy another Pixel 3a in near future.

I was wondering whether LibreOffice might be better on a Fairphone 3 than on a PinePhone with POS. There is a problem that LibreOffice hangs when it wants to recover files at start up, and I could not yet find a way to start LibreOffice when this questions box is on the screen, so it is not usuable for me to this date.

Thanks for your detailed answers, which I really appreciate.

I already have a ChromeCast 3 dongle which I used for an Android phone, and found out yesterday, that to use Chromium on PMOS has become easy. On my Windows PC, it was also very easy to mirror the screen over a ChromeCast to HDMI. I currently have VNC server connection between PinePhone and PC, but I think a WIFI to HDMI solution would be better. If I would buy a new device, I would prefer the Miracast standard, although I don t know whether desktop mirroring is as easy as with the Chrome browser.

I am also positive now about LibreOffice on the PinePhone. Jacob Crume, a Robotics student in New Zealand used linux-based PinePhone daily for a year:

https://news.itsfoss.com/pinephone-review/

He used four desktop environment, Plasma Mobile, Phosh and Lomiri, he spent roughly four months with each environment.

He was surprised at how capable the PinePhone was as a laptop. He said he often found myself editing documents in LibreOffice.

That is good news.

@fredldotme Chromecast is an interesting device if we do not have a working HDMI out, there are many options available, the easiest seems to be Chrome installation. Unfortunately, we currently use PinePhone with PostmarketOS, where it is not available anymore for this device, and since we run LibreOffice on it, we do not want to change as long as there is no better LibreOffice option available. We cannot donate, since we do not have a research grant either.

@emphrath Thank you for you answers.

We have currently managed to install LibreOffice on the PinePhone PostmarketOS. Unfortunately, Bluetooth mouse and keyboard are not stable, HDMI out: tested two adapter which did not work. One usb mouse worked, but not the PC keyboard over VNC server connectet to a Windows PC.

In LibreOffice, it is sometimes possible to type with the PinePhone keyboard, but LibreOffice is not touchable.

Pixel 3a is currently unavailable in Switzerland.

We love LibreOffice, but we are really desperate.

@doniks For the Google Chrome we think it would be possible to start a thread which is as long as this tread here about the Miracast:

https://forums.ubports.com/topic/7807/google-chromecast-installation-on-ubuntu-touch

For the Miracast, it has been evaluated how it works on Ubuntu Touch.

Unfortunately, we already have a Chromecast adapter. It is worth buying a Miracast and sell the Chromecast on ebay?

We have a Google Chromecast device and where very happy with it on an Android phone, a robust and stable mirroring of the phone sceen on a HDMI screen was possible. Unfortunately, there is no app available for Ubuntu touch. But there is a detailed instruction how to cast your GNOME Shell Desktop to a Chromecast (With Audio, Wayland / X11 Support) using cast to TV:

https://www.linuxuprising.com/2020/04/ho...op-to.html

There are several instructions for several Lunix distros. To install it on Ubuntu Touch, which one to choose? Ubuntu?

For the further part we agree with the comment of NOT.HUMAN:

«just post one command that will install everything, we dont have to time to go thru this long article ... for fcks sake ... you are complicating stuff that is already complicated ... this is why linux desktop is dying ....»
